We're going to begin this week with some Big Questions for our fact fanatics - I Love Books wrote a tremendously good review of 'Does my Goldfish know who I am?': and Hundreds More Big Questions by Gemma Elwin. This novel collates children's questions and provides answers by experts on the subject.

'When you see a general knowledge book you don't generally want to read it as most people assume that they are boring. I can officially inform you that this particular knowledge book is both informative AND funny … I would say it is for any age really, the sooner you know your general knowledge, the better!'

Another festive delight for our non-fiction fans, as Riffat wrote a superb review of How Your Body Works by Judy Hindley. And we're going to hand straight over to Riffat for our synopsis: 'This non-fiction book tells the reader all about the human body in very simple words. It starts from how the food is in taken from the mouth … and consumed by the different body parts which are then able to perform all the important functions for living. The book ends by explaining in simple words what the human body is made of.'

'I had previously read and learnt quite a lot about human body. The basic words used by Usborne, along with extremely colourful and loud imaginary illustrations by Colin King, made me feel rather overwhelmed … My six year old sister, however, seemed to have enjoyed going through the book. Therefore, I will recommend this book only to those children who absolutely have no knowledge beforehand, unlike a reader like me who was already quite aware. It will give them all the basic understanding about how the body works.'

Fiction now and what is more fictional than time travel?! Lottie Longshanks wrote a brilliant review of The Wells Bequest by Polly Shulman. In this story, when Leo sees an older version of himself in the past, he becomes involved in the New York Circulating Repository and meets a time travelling girl from the future called Jaya.

'This is a really interesting book that feeds your imagination and makes you think very hard … What I love about this book is the way in which all the amazing equipment that is used has its source in science fiction books that have already been written such as The Time Machine by H.G. Wells … In spite of their extraordinary abilities Leo and Jaya are very convincing likeable characters. I shall look out for more books by Polly Shulman.'

Elsewhere, ABitCrazy wrote a terrific review - more time travel! - of Time After Time by Tamara Ireland Stone. When time travelling Bennett from the present falls in love with Anna from the past, they must fight to keep their relationship alive.

'But I think the book was good even if it wasn't what I thought it was going to be. It wasn't better than I thought but it wasn't really disappointing like some books are … If you are a crazy romance fan this is definitely the book for you or if you just want a book to get lost in this book might help you. I will definitely suggest this to some of my friends and I suggest it to you too! 4 stars!'

Moving on to an intriguing supernatural tale, Firebird wrote an outstanding review of Nowhere by Jon Robinson. This story centres around a mysterious factory in the middle of nowhere - where a hundred teenagers are imprisoned for crimes they do not remember committing.

'The mystery of why they are really there is revealed piece by piece, keeping the reader on tenterhooks, desperate to find out the truth. Even whilst juggling six different main characters in a relatively short book, Robinson manages to make all the protagonists feel real and fully three-dimensional. The characterisation is subtle, without the black and white, villain and hero distinction of some children's books … the only problem with this book is that it finishes on a nail-biting cliff-hanger – and the sequel Anywhere doesn't come out until 2014!'

We're finishing on an old favourite of 2013 as Wizard wrote a fantastic review of Wolf Brother by Michelle Paver. As you know by now in this story the protagonists Torak embarks on a magical quest to slay a demon bear who disrupts the tranquillity of the forest.

'Wolf Brother is a tale about Torak's adventure through a shadowy world steeped in natural magic … I particularly like this book because of how engaging it is and I was so upset when I finished it. This may not be your genre of book but you will absolutely love it. Enjoy the book!'
